Abstract: PROBLEM TO BE SOLVED: To secure a frame rate similar to the case without a recovery period, that is, a short frame period by making a scanning voltage both voltages (positive and negative) of a pulse shape and simultaneously applying a recovery voltage higher than a hold voltage to a scanning electrode. SOLUTION: For successively scanning from scanning electrode Y1 to scanning electrode Yn, the voltage is applied to the scanning electrodes after the scanning electrode Y2 with a waveform shifting by a selection period. At this time, for preventing a flicker in a display, voltage polarity at every scanning electrode is constituted so as to be inverted such as that, e.g. the scanning electrode Y1 is positive, and the scanning electrode Y2 is negative,.... Further, respective recovery periods from the scanning electrode Y1 to Yj are provided at the timing that the selection period from the scanning electrode Y1 to Yj among the scanning electrodes Y1 to Yn is ended. The selection voltage of the selection period consists of both voltages of positive or negative pulse shape, and respective recovery periods of the scanning electrodes are provided at the timing that the selection period from the scanning electrode Y1 to Yj is ended.
